I have a 725EXI...

I have a 725EXI AWD Huskvarna mower that I cannot start. The pull was not right. I looked underneath and found that the blade was spinning freely. I could spin the blade and the belt pulley had no friction on the belt. Loose belt? Everything else appeared to be in place.

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

The belt should not move when the blade is turned by hand. That is a drive belt it should only be tight enough when the drive system is. The blade is attached to a blade adapter when you turn the blade by hand does it turn the engine

I just looked at it again. The belt is in place but the drive shaft spins freely. It appears that the shear pin between the drive shaft and the drive pulley has sheared. How do I get to the drive shaft sheer pin?

I understand that. The blade will not spin without rotating the motor. When I spin the blade it spins very freely and without trying to rotate the motor. Is there a sheer pin between the motor shaft and the pulley attachment?

I will tell you that...the things you have to go through to be an Expert are quite rigorous.
